DISPENSING-CAN.

Specification of Letters Patent.

Patented Nov. 2, 19115.

To all whom it may concern:

Be it known that I, FREDERICK M. FURBER, a citizen of the United States,residing at Revere, in the county of Suffolk and State of:Massachusetts, have invented certain Improvements in Dispensing-Cans,'of which the following description, in connection with the accompanyingdrawing, is a specification, like reference characters on the drawingindicating like parts.

This invention relates to dispensing cans and more particularly to suchcans designed to hold and dispense naphtha, benzin, or other highlyvolatile liquids.

In the manufacture of boots and shoes it is customary to employconsiderable quantities of benzin, naphtha, and the like for cleaningpurposes, and as such liquids are highly inflammable and subject toconsiderable loss through evaporation, it is desirable that dispensingreceptacles for such liquids be kept constantly covered and that meansto regulate the supply of liquid be provided.

- The object of the present invention is to.

improve and perfect such dispensing cans.

To this end an important feature consists in providing a receptaclewhich will be economical to construct, simple in operation and durable.

Another feature consists in an arrangement for keeping the contents ofthe receptacle normally covered while ready for use.

Another feature is an arrangement whereby a small quantity of liquid maybe dispensed at one time. I

Another feature is an arrangement whereby any unused liquid may drainback into the receptacle, and a further feature consists in adjustablemeans to regulate the quantity of liquid dispensed at each application.

In the preferred embodiment of the invention as herein shown, adispensing can is provided containing a reservoir and a shallow dip panor brush pan adjacent to the base of the reservoir, to which the liquidin the reservoir is fed by the barometic principle ina well-knownmanner. A cover for the brush pan is arranged" to be normally inposition to close the pan but it is yieldingly sustained so that aslight pressure upon the,

cover acts to displace it, whereby a supply of liquid may be obtained.Adjustable means is provided to regulate the amount of liquid obtainableat each displacement of the cover. An important advantage incident tothis construction is that the device is always ready for use and yet thecontents are kept constantly covered, thus reducing all chance ofevaporation and all danger of fire to a minimum. An additional advantageis that the supply of liquid is regulated without the usual provisionofvalves, no valves or pipe connections being used.

Other important features, details of construction and combinations ofparts will be hereinafter more particularly described and claimed.

The accompanying drawing illustrating a preferred embodiment of theinvention shows a vertical cross sectional view of the dispensing can.

The numeral 1 designates the main part of the receptacle containing thereservoir and an extension 2 is shaped to form a dip pan to which theliquid from the reservoir flows through a passage 5. The liquid from"the reservoir will flow through the passage 5 and into the dip pan untilthe level of the liquid rises above the entrance of the passage 5, whenfurther flow is stopped by the action of the air pressure. As the liquidis used up in the dip pan it drops below .the level of the entrance tothe passage 5 and the air then forces its way therethrough into thereservoir and the flow of liquid to the dip pan automatically takesplace, this being commonly referred to as the barometric feed principle.

In order to fill the reservoir in the part 1 of the receptacle, a roundthreaded aperture is provided, preferably in the base, in which acorrespondingly threaded plug 3 isfitted, having a suitable flange 4 sothat a washer 6 of leather, rubber, or the like, may be utilized'ifdesired to make a tighter joint. By providingthe filling plug in thebase, the receptacle is rendered more'nearly airtightthan if such a plugwere in the top above the level of the liquid. When the reservoir is tobe filled, it is necessary to re verse its position, allowing it tostand on its top portion, and therefore any liquid in the dip pan willbe returned to the reservoir,

and the receptacle may be similarly positioned when notlin use toprevent the liquid within the ring 9 which is provided with a slightlyprojectin flange on its upper part and against this flange the cover 10is held normally in contact by a spring 14 which may be conveniently setin a central recess 13 in the dip pan and arranged to encircle a lug orboss 16 formed on the central portion of the cover 10. The coverlO alsohas a raised rim 11 which may be formed integral upon its top surface orbe otherwise attached, which rim, by contact with the projecting flangeportion of the ring 9 steadies the movement of the cover and serves tomore effectually close the dip pan from the air and prevent evaporation.A plurality of holes 15 through the rim 11 are provided as shown.Pressure on the top of the cover 10, as for example by an operatorholding a sponge or cloth on the cover and pressing downwardly, movesthe cover into the liquid contained in the dip pan, displacing it andallowing it to flow around the edge of the cover 10, through the holes15 on to the top of the cover where the liquid may be ob-' sorbed by thecloth or sponge. When the pressureis released the spring 14 returns thecover 10 to its normally raised position, and any unused portion ofliquid will drain back into the dip pan-through the holes 15.

In order to regulate the depth to which the cover 10 may be depressedand consequently to determine the supply of liquid dispensed with eachdepression of the cover,

a stud 12 is threaded through the boss16 in the cover 10 and by propermanipulation of said stud the downward movement of the cover 10 islimited by contact of the stud with the bottom of the dip pan. The topof the stud-12 is provided with a slot so that a common screw-driver maybe used to rotate it and hence to adjust its position relatively withthe cover.

comprising a receptacle having a reservoir, a

. dip pan projecting from one side of said receptacle, a passageaffording a barometric feed between sald reservoir and said pan, a

substantially flat cover for said dip pan arranged when slightlydepressed to permit the liquid to flow over the top thereof, a

spring in said pan to press said cover in raised position to close thedip pan, said pan having a recess to receive and position said spring,and a ring supported bysaid pan arranged to overlie the margin of saidcover and to limit its upward movement.

device of the class described, comprlsing a reservoir to contain liquid,a dip pan arranged to be supplied by liquid from the reservoir by abarometric feed, a vertically movable cover for said dip pan, means fornormally holding said cover at the upper limit. of its movement andadjustable means to limit the movement of said cover.

3. A device of the class described, com-- prising areceptacle having areservoir, a dip pan, a. passage between said reservoir and dip pan, acover for the dip pan, a spring to hold said cover in raised position, a

flanged ring in the dip pan to limit the upward movement of the cover,and a threaded stud extending through the cover and projectingdownwardly to limit the downward movement of the cover.

4. A device of the character described comprising a reservoir, adip pan,a passage afiordmg a barometric feed between said reservoir and sald dippan, a coyer for said dip pan, resiliently held in raisedposition toaffording a barometric feed between said reservoir and said dip pan, acover for said dip pan, resiliently held in raised position,

and'a flange 5011 said cover having an aper ture therein.

6. A device of the character described, comprising a reservoir, a dippan having a barometric feed connection with said reservoir, adepressible supply pan acting when in normal position to close the dippan and constructed and arranged to-permit a small quantity of liquid toflow upon it when depressed, and means-establishing communicationbetween the dip pan and the top of the depressible supply pan to permitany unused portion of liquid to drain back into said'dip pan while saidsupply pan is returning to normal position.

7 A device of the character described comprising a dip pan, having anopen top;

a cover for said dip pan resiliently held in raised positionsubstantially fitting said top, whereby said dip pan is substantiallysealed, said cover constructed and arranged to be partially submersiblein the fluid contained in the dip pan said cover having .acircumferential raised portion on its upper surface, and havinga passageleading through said raised portion to a portion of said cover which isnot in communication with said dip pan except when the cover isdepressed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
